How should the drive to the LM267X ON/OFF pin be configured?

0

The ON/OFF pin (pin5) of the LM2675 is a normally ON switch (or active OFF). Internally to the voltage regulator, a Logic HI is provided to the regulator`s active circuits via a 7V zener which is powered through Vin (pin7). The minimum threshold voltage required to switch the regulator ON is 1.4V. The ON/OFF pin may be left open (no connection) to activate the regulator upon application of input voltage within the specified range of 6.5V to 40V.
